Looks like you followed the normal login link on the top right. That page also has a link to the home loan management portal, which is a different portal, you need to login with your loan account number and OTP sent to email/mobile.
So I got a ICICI EPM recently and tried a pre-payment, and sure enough I got the 3% rewards with ICICI EPM. 6012 MCC is not excluded for rewards in EPM. Not bad, can atleast use it for hitting the annual fee waiver threshold.
